Lowepro Backpack

I'm trying to find a bag to store all my stuff: D200 w / Nikon Grip 70-200 f/2.8 VR Nikon 50mm f1.8 Nikon 60mm f2.8 Nikon teleconverter 1.7 micro Sigma 18-50mm f2.8 15 "notebook right now I have a 4 Nova and its nice but 70-200 does not hold me or my laptop Bag Shoulder and my back hurts, so im thinking im going to need a backpack Lowepro makes great backpacks for camping, but their backpacks for cameras really suck in terms of shoulder straps and support ideas anyone?

Lowepro Stealth Reporter A D650AW fit all this (including the laptop) quite comfortably. It's a Shoulder Bag, though, so can not one of your other requirements. It would be worth checking out, however, because also has a waist strap which serves to distribute some of the weight above his waist. The waist strap is not enough to keep the bag itself, but me at least helps me to comfortably carry more weight than he could in a normal shoulder bag. It can often lead to 10-15 pounds of equipment in my D650AW, while I find 6-8 pounds a practical limit on the 4 Nova. By the way, I just bought the 4 Nova a few weeks ago. For what I bought it, I love it, although I recognize that not is a substitute for the larger exchanges.
